Express JS重定向到默认页面，而不是"Cannot GET".

问题描述：

我使用的是Express JS，我有一组定义如下的路由

I am using express JS and I have a set of routes that I have defined as follows

require('./moduleA/routes')(app);
require('./moduleB/routes')(app);

，依此类推.如果我尝试访问上述路由中未定义的任何路由，请说

and so on. If I try to access any of the routes that I have not defined in the above routes, say

http://localhost:3001/test

说

Cannot GET /test/

但是，除了这个，我想重定向到我的应用程序的索引页面.我希望这种重定向发生在所有未定义的路由上.我该如何实现?

But instead of this I want to redirect to my app's index page. I want this redirection to happen to all of the undefined routes. How can I achieve this?

答

尝试将以下路由添加为最后一条路由:

Try to add the following route as the last route:

app.use(function(req, res) {
    res.redirect('/');
});

经过一番研究，我得出结论，最好使用app.get代替app.use:

After a little researching I concluded that it's better to use app.get instead of app.use:

app.get('*', function(req, res) {
    res.redirect('/');
});

因为app.use处理所有HTTP方法(GET，POST等)，并且您可能不想使未定义的POST请求重定向到索引页.

because app.use handles all HTTP methods (GET, POST, etc.), and you probably don't want to make undefined POST requests redirect to index page.
